Custom context menus can now be added to bookmarks.The theme API now has support for colors.tab_text and colors.background_tab_text and can accept both Chrome arrays and CSS colors for all properties.Fixed a crash with webRequest.filterResponseData.🌟 QuanTakeuchi removed the unused mIconLoadingPricipal field!.🌟 86ecce74 helped us get rid of an unneeded XBL binding! Great to see another binding bite the dust.More fixes for migration performance incoming in the next weeks! Doug Thayer, while investigating reasons for slow migrations, largely improved the time needed to insert lots of visits at once.High-speed scrolling in the tab strip is buttery smooth again!.The site was ready the day before the 57 launch, and it took a ton of effort from everybody.
